The company also finalized a commercialization deal with Innovent Biologics to hand over mainland China sales rights for Verzenios, a CDK4 and 6 inhibitor approved for multiple breast cancer indications in the region. AbbVie ($ABBV) saw its market capitalization jump $43B over the past week, reflecting nearly 11% gains driven by acquisitions, new approvals, and pipeline expansion. The pharmaceutical giant completed an $11 billion acquisition as part of its strategy to plan ahead for patent cliff exposure. Pfizer ($PFE) closed at $24.08, down 1.19% in the latest session, with the stock showing a 21% total return decline over the past three years despite progress in IBRANCE and weight loss drug development.

Amgen ($AMGN) faces mounting regulatory pressure as the European Medicines Agency's Committee for Medicinal Products for Human Use recommended revoking Tavneos marketing authorization in the EU, while the New England Journal of Medicine retracted a trial supporting the $459 million drug.
